SPECIFICATION forming part of Letters Patent' No. 550,415,01ateaNovember 2e, 1895.

To all whom it may concern:

Be it known that I, PATRICK J; MADDEN, a citizen of the United States,residing at Chicago, in the County of Cook and State of Illinois, haveinvented certain new and useful Improvements in Water- Closets, of whichthe following is a specification, reference being had to theaccompanying drawings,which are made a part hereof, and in which- IoFigures l and 2 'are respectively a side and a rear elevation of theupper portion of the bowl of a water-closet embodying the invention.Fig. 3 is a horizontal section of a portion thereof on a somewhat largerscale, the

I 5 cutting-plane being indicated bythe line 3 3, Fig. l. Fig. 4 is ahorizontal section on a somewhat smaller scale than Fig. 3, but on asimilar plane, showing a modification.

The present invention relates to that class ze of water-closets in whichthe seat (or lid, or both seat and lid) is attached directly to thebowl; and the object of the invention is to provide an improvedattaching device. To this end the invention consists in the features 2 5of novelty that are particularly pointed out in the claims hereinafter.

In the drawings, A represents a portion of the bowl,and a an enlargementthereof,which, as shown, takes the form of a heavy rib or flangeextending horizontally across its back; but the shape of thisenlargement is not an essential feature of the present invention. Itsonly object is to insure sufficient strength at the points which receivethe strain from the attaching devices. It is a mere thickening of thetop of the bowl, and in the following specification it will not betreated as a distinct feature.

Referring to Fig. 3, A represents a portion of the bowl, having a socketcomprising a branch B,opening at the back of the bowl,and a branch O D,opening at the side thereof and intersecting the branch B. E is a part,hereinafter called an anchor, located in the branch B, and F is ascrew-bolt or similar device occupying the branch C D and passingthrough an eye formed through the anchor. Preferably that portion of thescrewbolt which occupies the eye of the anchor is 5o threaded andengages corresponding threads in the eye; but I desire to have itunderstood that in its broadest aspect my invention is not limited tothis construction, and in Fig. 4 a different construction is shown. Herethe bolt is threaded only at its end, and upon it fits a nut F', whichoccupies a socket G, which is formed in the back of the bowl and withwhich the branch D' (corresponding to the branch D of Fig. 3)communicates.

Referring to Fig. 3, H and I represent elas- 6o tic sleeves orbuffers,which iit upon the portions f and f of the bolt and iill the branch C D.The anchor has a stem J, provided with threads `which engagecorresponding threads in a socket j, which is formed in the end of abracket-arm J', the end of which is sufficiently large to span the openend of the socket. As shown in Fig. 4 this bracket bears immediatelyagainst the bowl; but as shown in Fig. 3 it bears upon it through the 7omedium of an elastic buffer K. The end of the bracket is provided with adepression f2, of somewhat greater diameter than the socket, and in thisdepression iits the buffer K, which is of greater diameter than thesocket, so that 7 5 its margin rests upon the margin of the socket andis compresssd between the bracket and bowl when the bracket is rotatedin the proper direction. I desire to have it understood, however, thatin its broadest aspect my in- 8o vention is not limited to these elasticbuffers H, I, and K, and in some instances they may, if desired, bedispensed with. They are, however, highly desirable when the bowl is ofearthenware, as they make a yielding connec- 8 5 tion and relieve thebowl of very much of the strain and concussion that would inevitablycome upon it if they were omitted, and to provide a more perfect devicefor attaching the seats or lids to bowls of vthis class is one 9o of theprincipal objects of the invention.

The construction above described is duplicated upon opposite sides ofthe bowl, as shown in Fig. 2. To the seat L are secured a pair of armsM, having at their extremities eyes m, 9 5 and to the lid N are secureda pair of arms O having at their extremities eyes o, said arms being solocated that the eyes J 2 of the bracketarms and the eyes m and o of thearms M and O come together end to end in sets of three, Ioe

so that a bolt P may be passed through each set, and thus the severalarms are hinged together.

Vhat I claim as new, and desire to secure by Letters Patent, is-

l. The combination with a bowl, of a pair of rotatively attachedbrackets, said brackets being detachable only by rotating them, and aseat hinged to the brackets and normally preventing their rotation,substantially as set forth.

2. The combination with a seat and b'owl having a socket, of an anchorsecured in said socket, a bracket adapted to bear upon the bowl andhaving rotative engagement with the anchor, said anchor and brackethaving engaging threads, so that by rotating the bracket it may bebrought to bear upon the bowl, and a seat hinged to the bracket andpreventing its rotation substantially as set forth.

3. The combination with a bowl having two sockets, of two anchors iitting in said sockets, two brackets having rotative engagement with theanchors and adapted to bear upon the bowl, the anchors and bracketshaving en gaging screw threads, so that by rotating the brackets theymay be brought to bear upon the bowl and the bowl thereby clampedbetween them and the anchors, and a seat hinged to the brackets andpreventing their further rotation, substantially as set forth.

Li. The combination with the seat and bowl, having a socket, of ananchor occupying said socket, a bracket having rotative engagement withthe anchor, and adapted to bear upon the bowl, and an elastic bufferarranged between the bracket and bowl, the anchor and bracket havingenga-ging threads, so that by rotating the bracket it may be brought tobear upon the bowl, through the medium of the butter, substantially asset forth.

5. The combination with the seat and the bowl having a socket, of ananchor occupying said socket, a bracket secured to the anchor, and anelastic buffer arranged between the bracket and bowl, the bracket havinga depression in which a portion of said buier fits, substantially as setforth.

G. The combination with the seat and theA bowl having a socket withintersecting branches, of an anchor arranged in one branch of saidsocket and having an eye registering with the second branch, a boltoccupying the second branch of the socket and the eye of the anchor, anelastic buer arranged between the bolt and the bowl and a bracketsecured to the anchor, substantially as set forth.

7. The combination with the seat and the bowl having a socket withintersecting branches, of an anchor arranged in one branch of the socketand having an eye registering with the second branch, a bolt occupyingthe second branch of the socket and the eye of the anchor, an elasticbuffer arranged between the bolt and the bowl, a bracket secured to theanchor, and an elastic buffer arranged between the bracket and the bowl,substantially as set forth.

8. The combination with the seat and the bowl having a socket withintersecting branches, of an anchor arranged in one branch of the socketand having an eye registering with the second branch, a bolt occupyingthe second branch of the socket and the eye of the anchor, an elasticbuffer arranged between the bolt and the bowl so as to allow the bolt alimited lateralmovement, a bracket having rotative engagement with theanchor, and an elastic buffer arranged between the bracket and the howl,t-he bracket and anchor having engaging threads so that by rotating thebracket it may be brought to bear upon the bowl through the medium ofthe buifer, substantially as set forth.
